`IMPROVEMENT IN COOKING-STOVES.

Specification forming part of Letters Patent No. 40,527, dated November 3, 1863.

Al Fig. 3, a horizontal section on the lineB,l

and Fig. 4 a plan of one. of the ovens.

The object of my invention is to provide a more complete and efficient cooking apparatus or stove. To realize this object I have con structed lthe following described apparatus, which I have found by experience to fulfil the end sought after-viz., to bake, broil, roast, and boil, all at one time and with one stove or The lower portion of this apparatus is represented in the drawings by A.

' lt is rectangular in form, and comprises the roasting-ovens, the furnace, and the broilingpan and grate.

B represents the furnace, lined with loose pla'es d d, or not, as circumstances may re quire.

a, is the grate of said furnace, fitted on a pivot in the center, that it may be shook to and fro by a lever (not shown in the drawings) to clear the furnace of ashes. The furnacedoor is shown by h.

C G are the roasting-ovens, of which there are four disposed all around the furnace, and the doors whereof are shown by E, Fig. 3, and a plan of which is shown by Fig. 4, and which, it will be seen, are made angular, so as to reflect and concentrate the heat toward the center thereof'.

C is the grate upon which the thing to be roasted is placed. This grate may be made to set horizontally, as at c, or it may be made to incline toward the back part ofthe oven, as at c', so as to give the thing roasted the full benefit of the heat radiated from the top and side plates ofthe oven, which are the hottest, being nearest the furnace. A revolving spit may also be used in these ovens, if it should be desired. I make the apparatus with both spits and grates.

e e are openings in the back of the ovens, through which the roasting fumes escape, and

t' fi are holes in the top of the oven-doors, to cause a draft through the ovens and ash-pit. By keeping the ash-pit door shut the draft for the furnace will be made to pass through the oven, by which means different things may be cooked in the ovens at the same time without tasting of each other.

D is a pan fitted in a receptacle made on the under side of the stove to receive it, and which serves the double purpose of ash-pan and broilingpan- Whenever it may be desired to broil anything the ashes are dumped out of said pan and a charcoal-fire is made therein under the gridiron, upon which the broilingis done, the fumes passing up through the fur nace-grate.

The boiler, making part of this apparatus,

is represented in the drawingsby E. It consists of a rectangularly-shaped tank or reservoir, arranged all around the three sides of' the upper part of themain furnace, either in one boiler or in three separate ones. In the furnace B there are three coils of pipes, G, placed to communicate with the said reservoir, from which the water has free circulation into said pipes, whereby the water is heated. In the top of said reservoirs a series of boiler or pot holes, H, are made, through which the bottoms of said pots or boilers are let down into the Water and boiled. These reservoirs should be sides thereof, the front side being occupied by y the oven-door L. rIhe plate M forms at once the lower end ofthe cylinder, the bottom plate of the bake-oven, and the top plate of the furnace. By these means the oven is very rapidly and evenly heated. There should be a hole, as at j', made near the top ofthe cylinder to clean the dirt off of thetop of the ov'en.

N represents a canopy, through which the draft-pipeKpasses, and in which pipes 0 are set p to carry off any steam or heatthat maybe generated about the apparatus when in operation. g g are resting-pieces made in the sides of the oven to set bake-pans, Ste., on.
